Title: Sand trap rake head
Inventor: COLONELLO ALEXANDER
IPC: A63B57/50
Filed: 1991-04-30
Granted: 1994-05-17
Abstract: A rake head having an elongate hollow body with an aperture in one side of the body.  A cylindrical plug extends through the aperture and across the inside of the body where it is anchored to the rake head by a screw.  The rake handle is fitted over the plug and held in place with another screw fastening the head,  the handle and the plug together.   The rake  head  has  a  row of tines  spaced along the body and projecting from it orthogonally with respect to the handle.          The tines are each rhombic in profile, with long diagonals aligned  transversely  of  the  body  and  short  diagonals substantially  perpendicular  to  the  long  diagonal.    This produces a reduced drag compared with cylindrical or other rounded tines.  The rake head has an octagonal profile with a trailing face adjacent the tines oriented at an obtuse angle with respect to the tines.

Title: Method and circuit for testing the conductive circuitry of a printed circuit board
Inventor: MUNIKOTI RAMACHANDRA
IPC: G01R31/28
Filed: 1991-05-17
Granted: 1995-08-15
Abstract: The reliability of conductive circuitry of a printed circuit board and particularly the integrity of the conductive  barrels of the through-holes is tested by cyclically passing a current through a plurality of interconnected barrels. The current must be sufficient to resistively heat the conductive barrels to a temperature at which the glass epoxy substrate adjacent to each barrel reaches a transition temperature at which the glass epoxy changes state from a solid to a semi-solid.  After sufficiently heating the glass epoxy, it is allowed to cool to ambient temperature.  This cycle is repeated for a predetermined number of cycles and the resistance of the barrels is measured after each cycle.  A measured resistance that exceeds a predetermined value indicates that one or more defects is present in the interconnected barrels.

Granted: 2000-09-12
Abstract: The arc extinguishing chamber (13) of a pole of an electrical circuit breaker with rotating arc and self-extinguishing expansion comprises an elongated housing (12), sealed off at both ends by end plates (17, 18). Coaxially inside the housing (12) there are disposed tubular contacts (14, 15) and a magnetic blowout coil (22). At the height of the extinguishing zone defined by the separation zone of the contacts (14, 15), there is located a sleeve (31) in proximity to the housing (12) while leaving an annular gap (32), which makes the top part (28) of the chamber (13) and the bottom part (29) of this chamber, located on either side of the extinguishing zone, communicate.      The gap (32) allows the gases to flow between these two parts (28, 29) and fins (30) arranged in this bottom part (29) slow down the rotation of the gases to direct them to the arc extinguishing zone.

Patent CA-2069710-C (CA)
Inventor: BIRD RAYMOND F
IPC: H04L29/06
Filed: 1992-05-27
Granted: 1996-08-20
Abstract: A Transport Layer Protocol Boundary (TLPB) architecture is described which will permit an application program to run over   a  non-native   transport  protocol  without   first generating a protocol compensation package tailored to the transport protocols  assumed by the program's  application programming  interface  and  by  the  available  transport provider.  All transport functions required by the program are converted to standardized or TLPB representations. When a connection between the first application program and a second  remote  application  is  requested,  the  individual required   TLPB   transport   functions   are   compared   to corresponding functions supported by the transport provider. Compensations are invoked only where there is a mismatch. The node on which the remote application program runs is informed   of   the   compensations   so   that   necessary de-compensation operations can be performed before the data is delivered to the remote application program.

Abstract: A control system for a vehicle powershift transmission includes a set of electrical connectors which, in a normal mode, permit electrical power to be transmitted to microprocessor-controlled valve drivers for the transmission clutch control valves.  These connectors may be swapped, in a limp-home mode, to permit power to be transmitted directly to the transmission clutch control valves.  In both modes, a start-in-gear protection circuit including a pair of relays and switches coupled to the shift lever prevents the vehicle from being started up with a gear engaged.  In the limp-home mode, a limp-home relay and a clutch disengaged switch prevents gear engagement until the operator has depressed and then released the clutch pedal, and the clutch pedal may be operated to modulate and control gear engagement.

Abstract: A system and method for establishing licensor changeable limits on shared software usage without the licensor having access to the system on which the shared software is running. An encrypted numerical limit value is embedded in the licensed software (program); when the program is executed ("accessed"), as a first step, the program decrypts the limit value and compares it to the number of users currently accessing the shared program. If the number of users is less than the limit, then access is allowed. If the number of users is equal to (or greater than) the limit, then access is denied.

IPC: G06F5/10
Filed: 1993-09-15
Granted: 2004-11-30
Abstract: An improved multi-stage synchronizer. The inventive synchronizer includes a first memory for storing data, a second memory means connected to the output of said first memory means for storing data, and a third memory for storing data connected to the output of said second memory means. The second memory includes a plurality of multi-stage first-in, first-out memory devices. In a particular embodiment, the first and third memories are implemented with synchronous single stage first-in. first-out memories. In a preferred embodiment, the first-in, first-out memories are designed to allow data to be read and written during a single clock cycle after the memory is full. This is achieved by adding an external read signal to the 'not full' signal generated by the device. The provision of single stage FIFO memories on either side of a multi-stage FIFO memory allows for lower set up time and output delay at higher operational speeds.

Title: Negative absolute conductance device and method
Inventor: DUTTA MITRA
IPC: H01L29/12
Filed: 1993-09-27
Granted: 1999-02-16
Abstract: Disclosed generally herein is a quantum wire embedded in another material or a quantum wire which is free standing.  The quantum wire structure is fabricated such that a quantum well semiconductor material, e.g. Gallium Arsenide (GaAS), is embedded in a quantum barrier semiconductor material, e.g. Aluminum Arsenide (AlAs).  Preferably, the entire quantum wire structure is engineered to form multiple subbands and is limited to a low dimensional quantum structure having dimensions around 150x250 .ANG..          This structure has a negative absolute conductance at a predetermined voltage and temperature.  Due to resonant behaviour of the density of states, the rates of electron scattering in the passive region (acoustic phonon and ionized impurity scattering as well as absorption of optical phonons) decrease dramatically as the electron kinetic energy increases.  In operation, an electric field and/or laser pulses inject electrons into the quantum structure; the electrons, then, exhibit transient negative drift velocities.  At injection energies which are a multiple of the optical phonon energy, the electric field forces the electrons from the negative part of the ?-space to the lower energy subbands, excluding them from re-emission.  Electrons from the positive part of the ?-space, however, emit optical phonons and are forced to bottom of the subband.  As a result, electrons with high negative velocity dominate over those electrons with high positive velocity and cause the current flowing against the applied electric field, otherwise known as negative absolute conductance.  This transient process lasts about 1 to 3 picoseconds in the field range of 100 to 500 v/cm.
